World famous Burpee Beer is brewed in the small town of West Burpee.

Currently, the town of West Burpee levies a $2 per-case tax on all Burpee Beer, and the brewery sells 25,000 cases a year at a total price of $20 per case. The mayor of West Burpee has decided to erect a statue of himself in the town square at a cost of $25,000, and wants to raise the money from additional tax revenue from sales of Burpee Beer. He has asked each of the three town council members to come up with a plan to raise the additional $25,000. Council member Simpson advises increasing the percase tax by $1. Council member Milhouse advises raising the tax by $2 per case. Council member Flanders advises reducing the current tax by $0.50 per case.

If the mayor chooses Simpson's plan, the total cases of beer that would need to be produced to increase tax revenue by exactly $25,000 is __________cases?
